TRACE-FASTENING FOR SINGLE-TREES.

SPECIFICATION forming part of Letters Patent No. 254,293, dated February 28, 1882,

Application filed January 2B, 1881.

To all whom it may concern: Y

g Be it known that I, LUGIUS S. EDLEBLUTE, ofthe city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Trace-'Fastenings for Single-Trees, ot' which the following is a specification.

My invention relates to that cla-ss of fastenings in which a bolt or equivalent device attached to theend of the single-tree is used for the purpose of securing the trace thereto, the objects of my improvements heilig to provide a bolt-fastening which, being simple in design, secures cheapness of construction and ease in the attachingand detaching ofits various parts to the single-tree. p

Figure l is a perspective view ot the invention shown attached to the end of a singletree with a trace fastened to same. Fig. 2 is a sectional elevation ofthe saine. Fig. 3 is a detached perspective view of the bolt shown in Figs. l and 2. Fig. 4 is a sectional elevation of a modification of the invention applicable also 'to neck-yokes. Fig. 5 is a detached perspective view of the holt shown in Fig. 4. Fig. Gis a perspective view of the end of a trace, showing the preferred form of `making the same.

Similar letters refer to similar parts in all iigures of the drawings.

A is the end of a single-tree, to which is attached the tube or casing B, holding the operating parts. This tube or casing B is provided with two ears or straps, one of which, C, is shown in Figs. l and 4, by which it is fastened to the end A of the single-tree either by a bolt or by any other suitable device. The bolt D has a shank, m, and is provided with a suitable thumb-piece, d, for operating the same, and is so constructed as to drop readily into place through the slot b in the casing B. This thumb-piece d is located some distance behind the shank m, and is connected to the latter by the plate u, which latter also serves to cover the slot in the casing through which the holtrod d and shank m have been introduced. The bolt-rod d works freely through the aperture b into the socket e of the lip or guard E, and when in use passes through the hole (No model.)

provided in the trace for holding the same. 5o The bolt D is also provided with a lug or projection,'d2, passing through the slot b ofthe casing B, to which may be 'fastened a strap or l line of any kind by means of a ring, as shown, or byany other suitable device, in order ,to operate the bolt from the seat of the vehicle or from any desired distance'. The boltD is held irmly to its place bythe spiral spring F, working against the piston G at the rear end of the bolt, and said spring is secured from slip- 6o ping by fitting into the recess or cup g of the piston G. The'bolt D is made with a projection or rivet, d3, to lit into a corresponding hole in the piston Cr, the shank m and rod d being first dropped into place in the casing B. The piston G is then introduced through the rear end of the casing and riveted to the bolt D by means ofthe aforesaid projection or rivet d3, as fully shown in Fig. 2. In the modified form shown in Figs. 4 and 5 this method of 7o fastening is dispensed with, and the piston G is made with and a part of the bolt D, being made small enough to permit of the bolt being dropped into place through the slot I) oi' the casing B.

The end A ofthe single-tree is provided with longitudinal slots a a, Fig. 1, at right angles to each other. This end is made slightly larger than the interior of the casing B, and is driven into thesame, the slotsaa giving spring enough 8o to the wood to permit it to enter,vand at the same time causing it to expand slightly when in place, and by binding upon the sides of the casing furnish an additional mode of fastening. The end A having been previously bored for the reception ofthe tube or bushing H, into which the spring F works, and the bushing being inserted therein, as shown, the construction of the end of the single-tree, when driven into the casing B, serves to bind and 9o secure this bushing in place. This bushing is made of sufcient strength to resist any action caused by shrinkage of the Wood, and, being made of suflicient size, affords a perfectly safe protection to the spring F, permitting it to act freely and Without any restraint whatever. The end of the single-tree is cut off at such a place as will give sufficient room in the interior of the casing B for the retraction of the bolt D, permitting it to fully elearthe space between the lip E and the end ofthe casing when said bolt is drawn back to permit of the insertion or removal ofthe end of the trace.

In the moditvd form as shown in Figs. 4 and 5, the bolt and piston are made in one piece, as heretofore described, with the exception that the thumb-piece d is made separate, and is pivoted to the body ot' the bolt by the pivot d4, as shown in the drawings, the object being to allow the thumb-piece d to be used as a latch or catch by being swung into the position shown by the dotted lines in Fig. 4, after the strap or trace has been secured by the bolt D. The lug or projection cl2 not being used in the modified form, the slot b in the casing B is dispensed with. The object of this modified form is to show a method oi' fastening applicable to ncck-yokes as Well as to single-trees.

A preferred method of making the end of tbe trace or strap to be used in connection with this invention is to fasten in the same an eyelet, I, of any approved form, having a hole, t', of suftcient size to permit the passage of the shaft of the bolt.

The mode ot' operation of my invention is as follows: When it is desired to fasten or unfasten the trace the bolt D is pulled back by means of the thumb-piece d or a strap attached to the lug 12 until the end of the rod cZ/fully clears the space between the lip E and the end of the casing B. The end of the trace is then placed in this space in such manner that the hole z' in the trace or strap is directly opposite the end ofthe rod d. rIhe hold is then released Vupon the thumb-piece (l, and the spring Fforces door-latch, so that when the traceis introduced between the lip and end of the easing, and

the rod d is partially retracted, and the edge y of the trace is pressed against the rod df, the bevels aid in retraoting the rod d and facilitate the introduction of the trace into a position where the rod d can enter the hole t' thereof.

What I claim as new and ot' my invention, and desire to secure by Letters Patent, is-

l. In a trace and yoke fastening device, the bolt d, attached to one side of the shank m, said shank having the piston G riveted to its opposite side, and being provided with plate n and thumb-piece d, in combination with the casing B, single-treeA,and spring I `,substantially as and for the purposes speciied.

2. rI lhe combination of the single-tree A, casing B, and fastening device D, constructed substantially as described, and provided with cup or piston Gr, spring F, and bushing H, substantially as described.

3. In a trace-fastening device, the shank m, provided with thumb'- piece l and bolt d and projection d2 and piston G, in combination with the single-treeA, casing B, and bushing H, substantiallyr as and for the purposes specified.

4. In a trace and yoke fastening device, the combination of a suitable bolt and devices for retraeting the same, and the spring F, bushing H, single-tree A, and casing B, substantially as described.

5. A sliding spring-bolt consisting ot' the shank m, provided with plate n and thumbpiece d and the bolt d and piston G, said bolt being actuated by a suitable spring, substantially as described.
